I attempted to download at the same time but didn't seem to take. Going back after playing the game once and redownloading worked. Not sure if that is necessary or not.

If you want to check, while the game is running (form KP and not HAT), say 'hey television' followed by 'let me choose'. All options should be the same color. If some are different, then you need the add-in.

You can also get Discovered (Intel sponsored) It is listed as Intel Discovered I believe. You can search for discovered and it will show up. Requires Kinect.
